Why Should You Invest In Double Glazing?

Energy Efficiency

Our A+ graded Double glazing boosts your building’s energy efficiency by adding more natural light and keeping warm air year-round.

Saftey & Security

Made with toughened glass and reinforced frames, double glazing is highly resistant to damage. Our fittings also include features like multi-point locking systems, which help enhance security even further.

Insulation

Unlike single panes, double glazing adds two thick layers of glass separated by a layer of Argon gas, which is a poor thermal conductor. This traps heat inside your building year-round and keeps the cold out.

Ventilation

Most double-glazed fittings, like sash and casement windows, come with added fan lights and versatile means of creating airflow within your building. By investing in double glazing you can increase airflow, which prevents condensation, dampness, mold, and stale air from forming.

Create Space

Adding a double-glazed extension is one of the best ways to add a light and airy space to your building that can be used for anything from storage to sitting areas for customers.

Versatility

Double glazing is a versatile investment that gives you the flexibility to keep your spaces cool or warm via various ventilation and hinge features. Additionally, double glazing saves you money on energy and upkeep costs all whilst being easy to maintain.

Case Study

Savs Southend

We had the great pleasure of working with SAVS Southend, a local CVS that works behind the scenes to help local charities and community groups.

When SAVS contacted us they were looking to replace their old, tired timber sash windows, which were in dire need of replacing. So we got to work. We replaced the old timber sash windows with some new uPVC verticle sliders, which not only look fantastic but also help Savs optimise their energy efficiency and security.

  • Boosted energy efficiency.
  • Enhanced insulation via double glazing.
  • Extra security was added with toughened glass and reinforced locks.
  • Added ventilation, that keeps the building cool in the summer and warm in the winter.
